Explain the significance of the expression E=lim (f) q ->0(q)

Asked by tejvir | 20th Aug, 2012, 10:17: AM

Expert Answer:

It means that q is a test charge.
A charge so small that it has negligiable influence on the electric field in its surroundings, and hence the system properties remain independent of position of charge.
